When are you going to release a firmware update for ZEN77 4.70 to update it for the newer for Updated SDK from 7.19.3 to 7.24.1? I see you did it for the 5.10 release.
Since the changes from h/w 4.xx to 5.xx were mostly cosmetic and product manufacturability/cost (i.e. no real form fit or function changes) you really shouldn’t strand the folks that invested in the 4.xx platform to not get the benefits of the 7.24.1 library. I have nearly 50 ZEN77s at 4.70.
I can appreciate you can’t go backwards to all the vintage of models but this rolling model change is different as mentioned above.
@CuriousB Just wanted to share a quick update on our plans for firmware updates.
We do plan to bring the same SDK update that was recently released for our newest generation of switches and dimmers to several of our earlier 800 Series models as well. Since these devices are also based on the 800 Series Z-Wave chip, they can be updated with the newer SDK through a firmware upgrade.
The planned releases include:
ZEN73 and ZEN74 (firmware 2.xx)
ZEN71, ZEN72, and ZEN76 (firmware 3.xx)
ZEN77 (firmware 4.xx)
These updates will be released gradually over the next few months as they complete testing and validation.
We’ll keep this thread updated as new firmware becomes available. In particular, we’ll post here as soon as the ZEN77 firmware 4.80 is ready for download.
Thanks got the file and updated 15 ZEN77s this afternoon.
Everything went fine except for the two LR devices which were last. When they came up for download the fragment size of the file went from 3855 to 1205 so I thought the system somehow substituted a wrong file for these last couple. In the end I guess it was a non issue, perhaps LR packets are larger meaning fewer of them are needed to transfer the file. In any event a brief moment of panic came upon me.
All devices are working fine and successfully updated. I have been having issues with “tortured routes” and I have found pairing without S2 security (ie no security) helps the devices behave better and I am hoping the new library optimizations take it another step forward.
No worries there! What you’re seeing with the packets is correct With S2A enabled on a mesh device, it is usually 5200 packets for OTA, without security you’ll see around 3800 packets, and for Z-Wave Long Range you’ll only see around 1200 packets for OTA, which makes it by far the fastest firmware update option.
